'''W''', or '''w''', is the twenty-third [[letter (alphabet)|letter]] of the [[Latin alphabet]], used in the [[English alphabet|modern English alphabet]], the alphabets of other western European languages and others worldwide. Its name in English is [[English alphabet#Letter names|''double-u'']],<ref group="in">Pronounced {{IPAc-en|ˈ|d|ʌ|b|əl|.|j|uː}} {{respell|DUH|bəl|yoo}} in formal situations, but colloquially often {{IPAc-en|ˈ|d|ʌ|b|ə|j|uː}} {{respell|DUH|bə|yoo}}, {{IPAc-en|ˈ|d|ʌ|b|j|uː}} {{respell|DUH|bew}}, {{IPAc-en|ˈ|d|ʌ|b|ə|j|ə}} {{respell|DUH|bə|yə}} or {{IPAc-en|ˈ|d|ʌ|b|j|ə}} {{respell|DUH|byə}}, with a silent ''l''.</ref> plural ''double-ues''.<ref>"W", ''Oxford English Dictionary,'' 2nd edition (1989); 'W", ''Oxford English Dictionary,'' 2nd edition (1989); ''[[Merriam-Webster's Third New International Dictionary of the English Language]], Unabridged'' (1993) [[Merriam Webster]]</ref><ref>Brown & Kiddle (1870) ''The institutes of grammar,'' p. 19. <br>''Double-ues'' is the plural of the name of the letter; the plural of the letter itself is written W's, ''W''s, w's, or ''w''s.</ref>

==Name==
Double-u, whose name reflects stages in the letter's evolution when it was considered two of the same letter, a double U, is the only modern English letter whose name has more than one syllable.<ref group="in">However, "Izzard" was formerly a two-syllable pronunciation of the letter '''[[<span class="ltr">Z</span>]]'''.</ref> It is also the only English letter whose name is not pronounced with any of the sounds that the letter typically makes in words, with the exception of [[<span class="ltr">H</span>]] for some speakers.

Some speakers shorten the name "double u" into "dub-u" or just "dub"; for example, [[University of Wisconsin]], [[University of Washington]], [[University of Wyoming]], [[University of Waterloo]], [[University of the Western Cape]] and [[University of Western Australia]] are all known colloquially as "U Dub", and the automobile company [[Volkswagen]], abbreviated "VW", is sometimes pronounced "V-Dub".<ref>{{cite web|last=Volkswagen|url=https://www.youtube.com/watch?v=qgEvy60bZYI| archive-url=https://web.archive.org/web/20060502184847/http://youtube.com/watch?v=qgEvy60bZYI| archive-date=2006-05-02|title=VW Unpimp – Drop it like its hot|website=YouTube|access-date=November 3, 2011}}</ref> The fact that many website URLs require a "[[www.]]" prefix has been influential in promoting these shortened pronunciations.{{citation needed|date=November 2021}}

In other [[West Germanic languages]], its name is monosyllabic: German {{lang|de|We}} {{IPA|/veː/}}, Dutch {{lang|nl|wee}} {{IPA|/ʋeː/}}.

The [[Latin alphabet#Classical Latin alphabet|classical Latin alphabet]], from which the modern European alphabets derived, did not have the "W" character. The "W" sounds were represented by the Latin letter "[[<span class="ltr">V</span>]]" (at the time, not yet distinct from "[[<span class="ltr">U</span>]]").

The sounds {{IPAslink|w}} (spelled {{angbr|V}}) and {{IPAslink|b}} (spelled {{angbr|B}}) of [[Classical Latin]] developed into the [[voiced bilabial fricative]] {{IPA|/β/}} between [[vowel]]s in [[Vulgar Latin|Early Medieval Latin]]. Therefore, {{angbr|V}} no longer adequately represented the [[voiced labial-velar approximant]] [[sound]] {{IPA|/w/}} of [[Common Germanic|Germanic phonology]].

[[File:Coat of arms of Vyborg.svg|thumb|upright|A letter W appearing in the coat of arms of [[Vyborg]]]]
The [[German language|Germanic]] {{IPA|/w/}} phoneme was, therefore, written as {{angbr|VV}} or {{angbr|uu}} ({{angbr|[[<span class="ltr">u</span>]]}} and {{angbr|[[<span class="ltr">v</span>]]}} becoming distinct only by the [[Early Modern period]]) by the earliest writers of [[Old English]] and [[Old High German]], in the 7th or 8th centuries.<ref>{{cite web|url=http://www.oxforddictionaries.com/words/why-is-w-pronounced-double-u|title=Why is 'w' pronounced 'double u' rather than 'double v'? : Oxford Dictionaries Online|publisher=Oxforddictionaries.com|access-date=November 4, 2011|archive-date=August 22, 2016|archive-url=https://web.archive.org/web/20160822083407/http://www.oxforddictionaries.com/words/why-is-w-pronounced-double-u|url-status=dead}}</ref> [[Gothic alphabet|Gothic]] (not [[Latin alphabet|Latin-based]]), by contrast, had simply used a letter based on the Greek [[Upsilon|Υ]] for the same sound in the 4th century. The digraph {{angbr|VV}}/{{angbr|uu}} was also used in [[Medieval Latin]] to represent Germanic names, including Gothic ones like [[Wamba, Visigothic king|Wamba]].

It is from this {{angbr|uu}} [[Digraph (orthography)|digraph]] that the modern name "double U" derives. The digraph was commonly used in the spelling of Old High German but only in the earliest texts in Old English, where the {{IPA|/w/}} sound soon came to be represented by borrowing the [[rune]] {{angbr|ᚹ}}, adapted as the Latin letter [[wynn]]: {{angbr|ƿ}}. In early [[Middle English]], following the 11th-century [[Norman Conquest of England|Norman Conquest]], {{angbr|uu}} regained popularity; by 1300, it had taken wynn's place in common use.

Scribal realisation of the digraph could look like a pair of Vs whose branches crossed in the middle: both forms (separate and crossed) appear, for instance, in the "running text" (in Latin) of the [[Bayeux tapestry]] in proper names such as EDVVARDVS and VVILLELMVS (or the same with crossed Vs). Another realisation (common in [[roundhand]], [[kurrent]] and [[blackletter]]) takes the form of an {{angbr|n}} whose rightmost branch curved around, as in a cursive {{angbr|v}} (viz. <math>\mathfrak{w}. </math>)<ref name="Flawed Typefaces">{{cite web|last1=Shaw|first1=Paul|author-link=Paul Shaw (design historian)|title=Flawed Typefaces|url=https://www.paulshawletterdesign.com/2011/05/flawed-typefaces/|website=Print magazine|access-date=June 30, 2015|archive-date=June 23, 2015|archive-url=https://web.archive.org/web/20150623071023/http://www.paulshawletterdesign.com/2011/05/flawed-typefaces/|url-status=live}}</ref><ref name="Berry Roundhand" /> It was used up to the nineteenth century in Britain and continues to be familiar in Germany.<ref group="in">Writing manuals that include it include [[Edward Cocker]]'s ''[https://archive.org/details/penstriumphacop00cockgoog/page/n16/mode/2up The Pen's Triumph]'' of 1658 and engravings of the [[roundhand]] calligraphy of Charles Snell and sometimes [[George Bickham the Elder|George Bickham]].

Thus, the shift from the digraph {{angbr|VV}} to the distinct ligature {{angbr|W}} was gradual and was only apparent in [[abecedarium|abecedaria]], explicit listings of all individual letters. It was probably considered a separate letter by the 14th century in both [[Middle English]] and [[Middle Low German|Middle German]] orthography. However, it remained an outsider, not really considered part of the Latin alphabet proper, as expressed by [[Valentin Ickelshamer]] in the 16th century, who complained that:

{{blockquote|Poor ''w'' is so infamous and unknown that many barely know either its name or its shape, not those who aspire to being Latinists, as they have no need of it, nor do the Germans, not even the schoolmasters, know what to do with it or how to call it; some call it ''we'', [... others] call it ''uu'', [...] the [[Swabians]] call it ''auwawau''<ref>"Arm w ist so unmer und unbekannt, dasz man schier weder seinen namen noch sein gestalt waiszt, die Lateiner wöllen sein nit, wie sy dann auch sein nit bedürffen, so wissen die Teütschen sonderlich die schülmaister noch nitt was sy mit im machen oder wie sy in nennen sollen, an ettlichen enden nennet man in we, die aber ein wenig latein haben gesehen, die nennen in mit zwaien unterschidlichen lauten u auff ainander, also uu ... die Schwaben nennen in auwawau, wiewol ich disen kauderwelschen namen also versteh, das es drey u sein, auff grob schwäbisch au genennet." cited after Grimm, ''[[Deutsches Wörterbuch]]''.</ref>}}

In [[Middle High German]] (and possibly already in late Old High German), the West Germanic phoneme {{IPA|/w/}} became realized as {{IPAblink|v}}; this is why, today, the German {{angbr|w}} represents that sound.

===English===
English uses {{angbr|w}} to represent {{IPA|/w/}}. There are also a number of words beginning with a written {{angbr|w}} that is [[silent letter|silent]] in most dialects before a (pronounced) {{angbr|r}}, remaining from usage in [[Old English language|Old English]] in which the {{angbr|w}} was pronounced: ''wreak, wrap, wreck, wrench, wroth, wrinkle'', etc. Certain dialects of [[Scottish English]] still distinguish this digraph. {{angbr|w}} represents a vowel sound, {{IPA|/oʊ/}}, in the word [[pwn]], and in the Welsh loanwords [[Cwm (landform)|cwm]] and [[crwth]] it retains the Welsh pronunciation, {{IPA|/ʊ/}}. {{angbr|W}} is also used in digraphs: {{angbr|aw}} {{IPA|/ɔː/}}, {{angbr|ew}} {{IPA|/(<span class="ltr">j</span>)uː/}}, {{angbr|ow}} {{IPA|/aʊ, oʊ/}}, wherein it is usually an orthographic [[allograph]] of {{angbr|u}} in final positions. It is the [[Letter frequency|fifteenth most frequently used letter]] in the English language, with a frequency of about 2.56% in words.

===Other languages===
In Europe languages with {{angbr|w}} in native words are in a central-western European zone between Cornwall and Poland: English, [[German language|German]], [[Low German language|Low German]], [[Dutch language|Dutch]], [[Frisian languages|Frisian]], [[Welsh language|Welsh]], [[Cornish language|Cornish]], [[Breton language|Breton]], [[Walloon language|Walloon]], [[Polish language|Polish]], [[Kashubian language|Kashubian]], [[Sorbian languages|Sorbian]], [[Wymysorys language|Wymysorys]], [[Resian dialect|Resian]] and [[North Germanic languages|Scandinavian dialects]]. German, Polish, Wymysorys and Kashubian use it for the [[voiced labiodental fricative]] {{IPA|/v/}} (with Polish, related Kashubian and Wymysorys using [[Ł]] for {{IPA|/w/}}, except in conservative and some eastern Polish speech, where Ł still represents the [[dark L]] sound.), and Dutch uses it for {{IPA|/ʋ/}}. Unlike its use in other languages, the letter is used in [[Welsh language|Welsh]] and [[Cornish language|Cornish]] to represent the vowel {{IPA|/u/}} as well as the related approximant consonant {{IPA|/w/}}.[[File:WondersoftheInvisibleWorld-1693.jpg|left|thumb|A 1693 book printing that uses the "double&nbsp;u" alongside the modern letter; this was acceptable if printers did not have the letter in stock or the font had been made without it.]]

The following languages historically used {{angbr|w}} for {{IPA|/v/}} in native words, but later replaced it by {{angbr|v}}: [[Swedish language|Swedish]], [[Finnish language|Finnish]], [[Czech language|Czech]], [[Slovak language|Slovak]], [[Latvian language|Latvian]], [[Lithuanian language|Lithuanian]], [[Estonian language|Estonian]], [[Ukrainian Latin alphabet|Ukrainian Łatynka]] and [[Belarusian Latin alphabet|Belarusian Łacinka]]. It is also used in modern systems of [[Romanization of Belarusian]] for the letter {{angbr|[[ў]]}}, for example in the BGN/PCGN<ref name=":0">{{Cite web |url=https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/811510/ROMANIZATION_OF_BELARUSIAN.pdf |title=Belarusian romanization (June 2019) (publishing.service.gov.uk) |access-date=November 16, 2021 |archive-date=October 6, 2021 |archive-url=https://web.archive.org/web/20211006223432/https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/811510/ROMANIZATION_OF_BELARUSIAN.pdf |url-status=live }}</ref> system, in contrast to the letter {{angbr|[[ŭ]]}}, which is used in the [[Instruction on transliteration of Belarusian geographical names with letters of Latin script]].

[[File:Kalevala1.jpg|thumb|left|Titlepage of the first edition of the ''Kalevala'', 1835]]
In Swedish and Finnish, traces of this old usage may still be found in proper names. In [[Hungarian language|Hungarian]] remains in some aristocratic surnames, e.g. [[Wesselényi (disambiguation)|Wesselényi]].

Modern [[German dialects]] generally have only {{IPA|[<span class="ltr">v</span>]}} or {{IPA|[ʋ]}} for West Germanic {{IPA|/w/}}, but {{IPA|[<span class="ltr">w</span>]}} or {{IPA|[β̞]}} is still heard allophonically for {{angbr|w}}, especially in the clusters {{angbr|schw}}, {{angbr|zw}}, and {{angbr|qu}}. Some Bavarian dialects preserve a "light" initial {{IPA|[<span class="ltr">w</span>]}}, such as in ''wuoz'' (Standard German ''weiß'' {{IPA|[vaɪs]}} '[<span class="ltr">I</span>] know'). The Classical Latin {{IPA|[β]}} is heard in the Southern German greeting ''Servus'' ('hello' or 'goodbye').

In [[Dutch language|Dutch]], {{angbr|w}} became a [[labiodental approximant]] {{IPA|/ʋ/}} (with the exception of words with -{{angbr|eeuw}}, which have {{IPA|/eːβ/}}, or other diphthongs containing -{{angbr|uw}}). In many Dutch-speaking areas, such as [[Flanders]] and [[Suriname]], the {{IPA|/β/}} pronunciation (or in some areas a {{IPA|/ɥ/}} pronunciation, e.g. Belgian-Dutch ''water'' {{IPA|/'ɥa:tər/}} "water", ''wit'' {{IPA|/ɥɪt/}} "white", ''eeuw'' {{IPA|/e:ɥ/}} "century", etc.) is used at all times.

In [[Finnish alphabet|Finnish]], {{angbr|w}} is sometimes seen as a variant of {{angbr|v}} and not a separate letter, but it is a part of official alphabet. It is, however, recognized and maintained in the spelling of some old names, reflecting an earlier German spelling standard, and in some modern loan words. In all cases, it is pronounced {{IPA|/ʋ/}}. The first edition of the ''[[Kalevala]]'' had its title spelled ''Kalewala''.

In [[Danish alphabet|Danish]], [[Norwegian alphabet|Norwegian]] and [[Swedish alphabet|Swedish]], {{angbr|w}} is named double-v and not double-u. In these languages, the letter only exists in old names, loanwords and foreign words. (Foreign words are distinguished from loanwords by having a significantly lower level of integration in the language.) It is usually pronounced {{IPA|/v/}}, but in some words of English origin it may be pronounced {{IPA|/w/}}.<ref>{{cite news|url=http://www.denstoredanske.dk/Sprog,_religion_og_filosofi/Sprog/Ortografi/w_W|title=W, w - Gyldendal - Den Store Danske|newspaper=Den Store Danske|access-date=November 7, 2017|archive-date=September 4, 2017|archive-url=https://web.archive.org/web/20170904141630/http://denstoredanske.dk/Sprog,_religion_og_filosofi/Sprog/Ortografi/w_W|url-status=live}}</ref><ref>{{cite web|url=http://www.svenskaakademien.se/svenska_spraket/svenska_akademiens_ordlista/saol_pa_natet/ordlista |title=Ordlista |access-date=January 29, 2015 |url-status=dead |archive-url=https://web.archive.org/web/20120824045619/https://www.svenskaakademien.se/svenska_spraket/svenska_akademiens_ordlista/saol_pa_natet/ordlista |archive-date=August 24, 2012 }}, page 1098</ref> The letter was officially introduced in the Danish and Swedish alphabets as late as 1980 and 2006, respectively, despite having been in use for much longer.

[[Elfdalian]] is a good example, which is one of many dialects where the [[Old Norse orthography|Old Norse difference]] between v ({{IPA|/w/}}) and f ({{IPA|/v/}} or {{IPA|/f/}}) is preserved. Thus "warg" from Old Norse "vargr", but『åvå』from Old Norse "hafa".

In the alphabets of most modern Romance languages, {{angbr|w}} is used mostly in foreign names and words recently borrowed (Italian ''il watt'', Spanish ''el kiwi''). In Spanish, Italian, and Portuguese, {{IPA|[<span class="ltr">w</span>]}} is a non-syllabic variant of {{IPA|/u/}}, spelled {{angbr|u}}. In Italian, while the letter {{angbr|w}} is not considered part of the standard [[Italian alphabet]], the character is often used in place of ''Viva'' (hooray for...), generally in the form in which the branches of the Vs cross in the middle, at least in [[handwriting]] (in fact it could be considered a [[monogram]]).<ref name="Zingarelli 1945 1713">{{cite book |last=Zingarelli |first=Nicola |title=Vocabolario della lingua italiana |edition=7 |year=1945 |publisher=Nicola Zanichelli |location=Bologna |page=1713}}</ref> The same symbol written upside down indicates ''abbasso'' (down with...). In French, {{angbr|w}} is also used mostly in foreign names and words recently borrowed such as ''wagon'' or ''week(-)end'', but in the first case it is pronounced {{IPA|[<span class="ltr">v</span>]}} (because of its German origin; except in Belgium, where it is pronounced [<span class="ltr">w</span>]) and in the second {{IPA|[<span class="ltr">w</span>]}}. In most northern French dialects the former {{angbr|w}} turned finally to {{angbr|v}}, but still exists as a remnant in the place-names of [[Romance Flanders]], [[Picardie]], [[Artois]], [[Champagne]], [[Lorraine|Romance Lorraine]] and sometimes elsewhere ([[Normandy]], [[Île-de-France]]), and in the surnames from the same regions. Walloon as it sounds conserves the {{angbr|w}} pronounced {{IPA|[<span class="ltr">w</span>]}}. The digraph {{angbr|ou}} is used to render {{angbr|w}} in rare French words such as ''ouest'' "west" and to spell Arabic names transliterated ''-wi'' in English, but ''-oui'' in French (compare Arabic surname [[Badawi]] / Badaoui). In all these languages, as in Scandinavian languages mentioned above, the letter is named "double v" (French {{IPA|/dubləve/}}, Spanish {{IPA|/'dɔble 'uβe/}}) though in Belgium the name {{IPA|/we/}} is also used.

In [[Indonesian language|Indonesian]], the letter "w" is called ''wé''. The letter names in Indonesian are always the same with the sounds they produce, especially the consonants.

The [[Japanese language]] uses "W", pronounced ''daburu'', as an ideogram meaning "double".<ref>{{cite web |url=http://no-sword.jp/blog/2006/06/let-pretending-to-be-injured-begin.html |title=Let the pretending to be injured begin |publisher=No-sword.jp |date=June 10, 2006 |access-date=November 4, 2011 |archive-url=https://web.archive.org/web/20110721183954/http://no-sword.jp/blog/2006/06/let-pretending-to-be-injured-begin.html |archive-date=July 21, 2011 |url-status=dead }}</ref> It is also used in internet slang to indicate laughter (like [[LOL#Commonly used equivalents in other languages|LOL]]), derived from the word ''warau'' (笑う, meaning "to laugh").

"W" is the 24th letter in the [[Filipino alphabet|Modern Filipino Alphabet]] and has its English name. However, in the old Filipino alphabet, [[Abakada]], it was the 19th letter and had the name "wah".{{fix|text=is that 'h' a glottal stop?}}<ref>"W, w, pronounced: wah". ''English, Leo James Tagalog-English Dictionary''. 1990., page 1556.</ref>

In [[Washo language|Washo]], lower-case {{angbr|w}} represents a typical {{IPA|/w/}} sound, while upper-case {{angbr|W}} represents a [[Voicelessness|voiceless]] w sound, like the difference between English ''weather'' and ''whether'' for those who maintain the distinction.
